Rob is correct: Any group of people can register as a USMS "club". It's not the decision of the LMSC.
It's also not required that a swimmer who swims at a particular pool has to register with a particular USMS "club"*. For example, just because Phil swims in Menlo Park doesn't mean that he has to register an attachment to the Menlo Masters USMS club. He could register "unattached" or with any other club he chooses to align with. He doesn't even need to register with USMS through the Pacific LMSC. The only requirement for Phil is that if he wants to align with a club, he must register in (or transfer his membership to) the same LMSC that also registered the club.
Likewise, if anyone out there wants to swim in a relay with Phil, you can register an attachment to Menlo Masters or whatever club to which Phil has attached.
*Unless it's a condition of being a dues-paying participant in an organization's workouts that you must profess an attachment to that organization on your USMS registration. I'm not aware of an organization that demands this, though I assume that there are.
